One instance has been called to the attention of the Commission where the names of visitors to the fair, registered at a State building, are being forwarded to the leading daily papers of the State, and published as a matter of news in their columns. The papers in question not only publish the list of arrivals at the exposition, but have called for any other matter of interest occurring here relating to the people or affairs of the State. This method of publicity pursued by the commissioners of one State might, as the result of conference, become generally adopted. The Exposition Company could well afford to aid and assist in the preparation of descriptive articles, accompanied by plate matter, relating to different localities, because it is evident that the creation of interest in any locality will contribute to the general purpose. But it is not the intention to here attempt to detail the many ways of securing merited publicity which would undoubtedly evolve from a general conference by representatives of all the interested forces. The commissioners representing the various States and governments are persons of wide experience and broad intelligence; and they are all, in their respective spheres, undoubtedly as anxious to contribute to the success of the exposition as the directors and officers of the Exposition Company are known to be. It is far from the intention of the Commission to interfere with the operation of any of your own matured plans; but it is respectfully submitted that the failure of expected and necessary attendance at the exposition is a matter of such supreme importance as to warrant the employment of every available force connected with this enterprise in the work of calling public attention to the exposition through the press of the whole country, and such other agencies as may be suggested and adopted. Very respectfully, Thos. H. CARTER, _President_. Hon. D.R. FRANCIS, _President Exposition Company, Building_. The exposition management did not elect to avail itself of the cooperation of the National Commission in the matter of exploitation, but very shortly after the foregoing letter was delivered the advertising department became more active by advertising in the newspapers and by the use of billboards in St. Louis and the adjacent territory. The National Bill Posters' Association, which met in St. Louis about this time, observing the inadequacy of the provision made for advertising, volunteered to cooperate with the Exposition Company by posting bills on their boards free of charge throughout an extensive area.
